Abstract

This paper presents the analyses of the influence of the weak layers on the excavation-induced deformation in the sub-sea tunnel. The finite element software ABAQUS is adopted to investigate the stability of the surrounding rock in the case of inclined weak layers with various angles, and the stress and displacement fields of the surrounding rock are derived. The results show that the effects of the weak layer on the stability of the surrounding rock are more significant for a weak layer with smaller inclination angle. The weak layer has the largest influence on the stability of the tunnel when it located at the bottom of the tunnel.
